Ehrhart Polynomial
In mathematics, an integral polytope has an associated Ehrhart polynomial that encodes the relationship between the volume of a polytope and the number of integer points the polytope contains. The theory of Ehrhart polynomials can be seen as a higher-dimensional generalization of Pick's theorem in the Euclidean plane. These polynomials are named after Eugène Ehrhart who studied them in the 1960s. Definition Informally, if is a polytope, and is the polytope formed by expanding by a factor of in each dimension, then is the number of integer lattice points in . More formally, consider a lattice \mathcal in Euclidean space \R^n and a -dimensional polytope in \R^n with the property that all vertices of the polytope are points of the lattice. (A common example is \mathcal = \Z^n and a polytope for which all vertices have integer coordinates.) For any positive integer , let be the -fold dilation of (the polytope formed by multiplying each vertex coordinate, in a basis for the ...

Gustav Ehrhart
Gustav Ehrhart (21 December 1894 – 11 December 1971) was a German chemist. He synthesized the first fully synthetic opioid analgesic, methadone, together with Max Bockmühl. Education and professional positions Ehrhart studied chemistry at the University of Heidelberg, with a focus on organic chemistry. His studies were interrupted by the First World War. He served as an artillery officer. After the war he resumed his studies and was awarded a doctorate degree in 1922. One of his professors was Theodor Curtius. Ehrhart received the Victor-Meyer Award for his dissertation. In 1923 he started working for Hoechst AG. Two years later he became the deputy of Max Bockmühl, the head of the pharmaceutical research laboratories of the company. In 1949, after the Second World War, Erhardt succeeded Bockmühl as the head of the entire pharmaceutical research division of Hoechst AG. In 1951 he became a deputy member of the Board, and two years later a regular member of Hoechst AG's Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jakob Friedrich Ehrhart
Jakob Friedrich Ehrhart (4 November 1742, Holderbank, Aargau – 26 June 1795) was a German botanist, a pupil of Carl Linnaeus at Uppsala University, and later director of the Botanical Garden of Hannover, where he produced several major botanical works between 1780 and 1793. Ehrhart was the first author to use the rank of subspecies in botanical literature, and he published many subspecific names between 1780 and 1789. In 1779, Carl Peter Thunberg (1743–1828) named a genus of grasses, ''Ehrharta'', in Ehrhart's honor. Publications * ''Chloris hanoverana'', 1776. * ''Supplementum systematis vegetabilium, generum et specierum plantarum'', 1781. * ''Beiträge zur Naturkunde, und den damit verwandten Wissenschaften, besonders der Botanik, Chemie, Haus- und Landwirthschaft, Arzneigelahrtheit und Apothekerkunst'', seven volumes (1787 to 1792) – Contributions to natural history, etc. * Autobiography in Usteri's Annals of Botany.List of publications copied from an article on Jako ...

Surnames From Given Names
In some cultures, a surname, family name, or last name is the portion of one's personal name that indicates one's family, tribe or community. Practices vary by culture. The family name may be placed at either the start of a person's full name, as the forename, or at the end; the number of surnames given to an individual also varies. As the surname indicates genetic inheritance, all members of a family unit may have identical surnames or there may be variations; for example, a woman might marry and have a child, but later remarry and have another child by a different father, and as such both children could have different surnames. It is common to see two or more words in a surname, such as in compound surnames. Compound surnames can be composed of separate names, such as in traditional Spanish culture, they can be hyphenated together, or may contain prefixes. Using names has been documented in even the oldest historical records. Examples of surnames are documented in the 11th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
